Mouldmaster British Gypsum Fine Casting Plaster 1Kg, White, 20 x 15 x 1 cm

I did a cast, for a dog paw imprint, as per attached photo.3d printed a flexible cylinder, some masking tape to hold it.Wiped cooking oil on the imprint 3 times and voilà.The imprint seems to be made of modeling clay.After an hour or two I was able to take them apart.Good quality, easy to use, dries quickly, value for money.I went with 10% extra water, to have the mix more watery.Happy with my purchase.

Fantastic plaster that makes casting a dream. No airbubbles in the process, it mixes in easily with water creating fine pastw . It was touch hard after 1 hour as advertised but I should have kept it a bit longer in the mould as it was still not completely dry. Also for fine bits it probably should be reinforced with some fiber. Overall it is perfect for silocone mould casting as a hobby craft and for professional use. I will definitely order more!

The media could not be loaded. Used the entire 1kg bag as it was my first time and could be asked to use less and have to work out the water ratio.Im a XL Glove size and my wife is Small. Both our hands use approx 90% of the plaster mix. I also use about 730ml of water, not the 750ml as i wanted to make sure it set harder and not soft for the fi4st time.

It’s plaster - what else!

Great product which gave a superb smooth finish, ideal for Model Railway buildings and scenery, thank you. TM.
